I'd really like to know the original version of the joke-phrase, oft customized for signs or whatever, most notably used in one episode of the Simpsons:
"Bartenders do it 'till you barf"
Other versions I've seen include "Rogues do it from behind" (Penny Arcade) and "Milkmen do it on your doorstep" (Father Ted).
Can anyone shed light on this?
